Abstract
Animal model is a type of mixed-effects model, where covariance among data points comes from genetic and environmental effects. In this paper, the multivariate normal distribution is assumed for the genetic random effects. A new approximate maximum likelihood method is proposed to obtain the estimates of the genetic variance components and heritability. The effectiveness of the proposed method is illustrated through a simulation study.
